Areas of expertise


Dr Rob Simmons has over 20 years theoretical understanding and practical experience of soil erosion processes, diffuse pollution control and environmental modelling. This has been achieved through MSc and PhD research (1991-1998), 10 years working in Southeast and South Asia (1998-2008) and in his current role as Lecturer in Soil Erosion and Conservation. Of the 10 years overseas, seven were spent at the International Water Management Institute coordinating major donor funded national and regional projects with a range of partners including government organizations, international bodies such as WHO, UNESCAP and FAO, other CGIAR (Consultative Group for International Agricultural Research) Centres such as ICRISAT and ILRI, and NGOs, CBOs, private enterprises and agricultural communities.

Current activities

Dr Simmon's research experience is broad ranging. This includes the effect of polyacrylamide-based soil conditioners on soil structural sealing at a sub-process level, soil erosion risk assessment, modelling the off-site impacts of heavy metal contaminated sediments on food and human health, modeling heavy metal uptake to rice and other tropical field crops, phytoremediation of cadmium, mitigation of diffuse pollution and the safe agricultural use of wastewater. Studies have also included macro-nutrient loading, trace element deficiencies/toxicities and salinity management.
